Recovering lost or deleted files from an external hard drive on a Mac can seem like a daunting task, but with the right tools and methods, it can be done efficiently and successfully. Whether you’ve accidentally deleted important documents, experienced a disk failure, or lost files due to corruption, there are various recovery methods you can explore. This guide will provide you with a comprehensive, step-by-step approach to recovering files from an external hard drive on your Mac.
1. Problem
Before diving into the recovery process, it’s essential to understand why and how files can be lost from an external hard drive. Here are some common reasons:
Accidental Deletion: Files can be deleted accidentally, whether through a system error or human mistake.
Drive Corruption: External hard drives can become corrupted due to improper ejection, physical damage, or software issues.
Disk Formatting: Formatting your external hard drive can erase data, leaving you with an empty drive.
File System Errors: If the external drive’s file system becomes unreadable (e.g., HFS+ to APFS conversion issues or partition problems), it may lead to data loss.
Malware or Viruses: Although Macs are less prone to malware, it’s not impossible for an external hard drive to be infected, leading to data loss.
The good news is that most data loss scenarios can be remedied with the right tools. In the next sections, we will walk through several methods to retrieve your lost files.
2. Step 1: Check the Basics
Before jumping into more complex recovery methods, ensure that the issue is not simple. Check these basics:
Connection: Ensure the external hard drive is properly connected to your Mac. Try reconnecting the drive to a different port or using a different cable.
Power: If your external hard drive is powered by an external source (e.g., an adapter), check whether the power supply is working.
File System Compatibility: Confirm that your external hard drive’s file system is compatible with macOS. Macs typically support FAT32. exFAT, and HFS+ file systems, but NTFS (used by Windows) requires additional software or drivers to read/write.
Visibility: Open Finder and see if your external drive shows up. If it doesn’t appear, check if the drive is listed in Disk Utility (Applications > Utilities > Disk Utility).
If your external hard drive is visible but the files are missing, then file recovery is your next step.
3. Step 2: Use Time Machine (If Set Up)
Time Machine is Apple’s built-in backup software, which automatically creates backups of your Mac and external devices. If you had Time Machine set up for the external hard drive, recovering your lost files could be as simple as restoring from a backup.
Steps to Recover with Time Machine:
Connect your external hard drive to the Mac if it’s not already connected.
Open Finder and navigate to the location where the lost files were previously stored.
Open Time Machine from the menu bar or by searching for it in Spotlight.
Time Machine will display a timeline of backups. Scroll through and find a backup that includes the files you want to recover.
Select the files and click Restore.
This method only works if you had Time Machine backups set up. If not, you’ll need to move on to other recovery options.
4. Step 3: Check for Hidden Files
If you can’t find the files in your external hard drive, they may be hidden due to system or application behavior. macOS hides certain files by default.
Steps to Check for Hidden Files:
Open Finder and navigate to the external hard drive.
Press Command + Shift + Period (.). This shortcut toggles hidden files on or off.
If hidden files exist, they will appear, and you can drag them back to a visible folder.
5. Step 4: Use Disk Utility for File System Issues
Sometimes, file loss is due to a corrupted file system. Disk Utility is a built-in macOS tool that can help repair minor disk issues.
Steps to Repair the Disk:
Open Disk Utility from the Applications > Utilities folder.
Select the external hard drive from the list on the left.
Click on First Aid and then click Run. Disk Utility will scan and repair any issues it finds with the drive’s file system.
After the repair process completes, check if your files are accessible.
If Disk Utility doesn’t fix the problem, then data recovery software or professional services may be necessary.
6. Step 5: Use Data Recovery Software

7. Step 6: Seek Professional Help
If software recovery methods fail, you may need to seek professional data recovery services. These experts specialize in recovering data from physically damaged or severely corrupted external hard drives.
When to Consider Professional Help:
If the external hard drive makes strange noises or is not recognized by your Mac.
If the external hard drive has sustained physical damage (e.g., dropped or exposed to water).
If software recovery methods have failed to recover important data.
If the external hard drive has been formatted and standard recovery methods didn’t work.
Professional recovery can be expensive, but it is often the last resort for recovering critical files.
8. Preventing Future Data Loss
While data recovery is possible, prevention is always better than cure. To avoid losing files from your external hard drive in the future, consider these tips:
Regular Backups: Set up regular backups using Time Machine or another backup solution.
Proper Ejecting: Always eject your external hard drive properly before unplugging it to prevent corruption.
Drive Health Monitoring: Use disk health monitoring tools to check the condition of your external drive and catch potential issues before they lead to data loss.
Multiple Copies: Keep multiple copies of important files in different locations (e.g., external hard drives, cloud storage).
